BEST MODE FOR CARRYING OUT THE INVENTION

FIG. 1 shows a schematic view of a game machine to which one embodiment of an input device of the present invention is applied. The game machine 1, which is installed in a commercial facility and the like, is configured as a game machine providing a player with a playing chance in exchange of consumption of a predetermined amount of play value. In the game machine 1, a chassis 2 is provided. At the front side of the chassis 2, a control panel part 3 is provided. In the control panel part 3, an interface unit 4 is provided in an inclined condition like a rising slop from a front edge thereof to an end edge thereof. The interface unit 4 is one unit into which display function and input function are integrated. The height of the interface unit 4 is set in a range that an adult player of standard-tall can put naturally his/her fingers on the interface unit 4. Additionally, the inclination angle to a horizontal plane of the interface unit 4 is inclined to the horizontal plane, in such a manner that the player faces the interface unit 4 when looking down diagonally forward with a kind of bent-over posture. The interface unit 4 is partitioned by an input display part 4 a as a first display part and a multi purpose display part 4 b as a second display part. In the input display part 4 a, sixteen pieces of push button parts 4 c are provided in such a manner that they are arranged in the shape of a matrix having 4 rows and 4 columns.

FIG. 2 shows a plane view of the interface unit 4, and FIG. 3 shows a sectional view of the interface unit 4 of a set-up condition, the sectional view being along the line III-III shown in FIG. 2. As shown in these drawings, the interface unit 4 has a monitor 10 as a display apparatus and an input module 11 as an input device. As an example of the monitor 10, a liquid crystal display is employed, which has a display surface 10 a the aspect ratio of which is set to sixteen to nine or the neighborhood thereof and is put on the market as a PC monitor. Of course, not only the liquid crystal display, various kinds of display such as an EL display and an LED display can be employed as the monitor 10. On the back surface of the monitor 10 (the lower surface in FIG. 3), a terminal part 10 b is provided to connect video cables or the like.

FIG. 4 shows a sectional view of the interface unit 4 of a disassemble condition, and FIG. 5 shows an exploded perspective view of the input module 11. As shown in these drawings, the input module 11 is structured as an assembled part obtained by combining a base 12, a lattice base 13, panel substrates 14, a lattice panel 15, push button panels 16, rubber contacts 17 as plastic elastic bodies with electrodes, a button cover 18 and a lattice cover 19. The base 12 is a part functioning as a basal plate for joining the whole of the input module 11 and the chassis 2. The size of the base 12 (a vertical and horizontal size) is set in a range that can cover completely the display surface 10 a of the monitor 10. The base 12 is configured as, for example, an opaque part obtained by applying sheet-metal processing to a metal plate. However, as long as the base 12 is composed of opaque material, it is not necessary that the base 12 is a metal product. In the base 12, for recognizing screen image in the monitor 10, 16 pieces of square-shaped button perforated parts 12 a and a single display perforated part 12 b are provided. The button perforated parts 12 a are first perforated holes corresponding to the push button parts 4 c on one-to-one, and are arranged in the shape of a matrix having 4 rows and 4 columns. The display perforated part 12 b is a second perforated hole corresponding to the multi purpose display part 4 b. The display perforated part 12 b is in the shape of a rectangular, the width of which is slightly smaller than a entire width (the size in the right-left direction) of the display surface 10 a of the monitor 10. At each of both sides of the base 12, a folding back part 12 c is formed. The folding back parts 12 c are provided to fix the input module 11 to the chassis 2.

The lattice base 13 is a flat-plate-shaped base board to ensure rigidity of the input module 11. The whole of the lattice base 13 is composed of transparent plastic. The size of the lattice base 13 is set to a degree that can cover the whole of the base 12 except the folding back parts 12 c. The panel substrate 14 is a printed-wiring assembly for connecting electrically a control unit 30 (FIG. 1) of the game machine 1 to each rubber contact 17. Each of the panel substrates 14 is disposed on the lattice base 13 so as to be shared by two of the pushbutton parts 4 c, one push button part 4 c is disposed on the outer periphery of the input module 11 and the other push button part 4 c abuts on the other one inward. Accordingly, the number of the panel substrates 14 is eight in total. By sharing sixteen pieces of the push button parts 4 c by plural panel substrates 14 in this way, it is possible to make lessen trouble to be required because of a fix or an exchange in the case when a part of the panel substrate 14 does not work. Moreover, as each of four push button parts 4 c disposed in a center part of the input display part 4 a and the push button part 4 c abutting on the outer periphery of the four push button parts 4 c are mounted to the same panel substrate 14, the electric wiring circuit for each of the push button parts 4 c disposed in the center part is provided so as to reach the outer periphery of the input module 11, and it is possible to install wiring to the push button parts 4 c at the outer periphery of the module 11. In addition, the panel substrates 14 has also perforated parts 14 a corresponding to the push button parts 4 c on one-to-one.

The lattice panel 15 is a partitioned member for partitioning the display surface 10 a into plural areas corresponding to the push button parts 4 c respectively. The lattice panel 15 is constructed by combining in the vertical and the horizontal direction in a reticular pattern, frames 15 a composed of opaque plastic. The above mentioned panel substrate 14 extends up to the outer periphery of the module 11 along the frame 15 a in such a manner that the panel substrate 14 is covered by the frame 15 a. Between the frames 15 a of the lattice panel 15, sixteen pieces of void parts 15 b are provided in the same way as the button perforated parts 12 a in the base 12. The push button panel 16 is provided as a part to accept a push-down operation by a player in the input display part 4 a. The push button panels 16 is disposed to the void parts 15 b of the lattice panel 15 one by one.

As shown in FIGS. 6 to 8, the push button panel 16 has a panel main body 16 a (the hatched part) in the shape of a substantial square flat plate, and a flange 16 b disposed at the lower surface side of the panel main body 16 so as to rim the periphery of the panel main body 16 a. At each of four corners of the flange 16 b, an extended part 16 c is provided as apart of the flange 16 b, the extended part 16 c protruding outward in the diagonal direction of the push button panel 16. At the back surface (lower surface) side of each extended part 16 c, a recessed part 16 d in the shape of a circle is formed. The push button panel 16 is composed of transparent plastic, and mirror-like finishing was applied to the front, back and side surfaces of the panel main body 16 a. Thereby, the panel main body 16 a has a transparency enough high to recognize clearly the screen image in the monitor 10 therebelow. The panel main body 16 a corresponds to an operation part of the push button part 4 c. Blasting process was applied to the flange 16 b (including the extended part 16 c). Thereby, the transparency of the flange 16 b is lessened to a state of a fogged glass. The transparency of the flange 16 b is lessened in order not to see the panel substrate 14, the rubber contact 17, and the base 12 disposed under the push button panel 16 through the panel main body 16 a.

Returning to FIGS. 4 and 5, the rubber contact 17 is a part in which the electrodes for detecting the push-down operation of the push-down panel 16 are embedded in the rubber as the elastic body as supporting means which supports the push button panel 16 in an up-and-down movable manner at the four corners. When the rubber contact 17 is compressively deformed by the push-down operation to the push-down panel 16, the inside electrodes conduct electricity, and when the compressive deformation is released, the conduction by the inside electrodes is released. As this kind of rubber contact 17, the one on the market can be employed. The button cover 18 is provided to protect the inside of the input module 11 from ingress of gist and dust, where a void part 18 a is formed for exposing the panel main body 16 a of the push button panel 16. The button cover 18 is an opaque part, for example, being composed of plastic. The lattice cover 19 is provided as a facing panel for partitioning the push button parts 14 c, where void parts 19 a are also formed for exposing the panel main bodies 16 a of the push button panel 16. The lattice panel 16 is an opaque part, for example, being composed of metal.

FIG. 9 shows an enlarged view of IX portion shown in FIG. 3. Apparently as shown in FIG. 9, in the input module 11, the lattice base 13 is overlaid on the upper surface of the base 12, and on the upper surface of the lattice base 13, the panel substrate 14 and the lattice panel 15 are overlaid. At each of the void parts 15 b in the lattice panel 15, the rubber contact 17 is disposed so as to be overlaid on the panel substrate 14. The push button panel 16 is attached on the rubber contact 17 in such a manner that the recessed part 16 d in the extended part 16 c is engaged with the top part of the rubber contact 17.

FIG. 10 shows a plane view showing a state that the push button panel 16 is disposed in the void part 15 b of the lattice panel 15, FIG. 11 shows an exploded perspective view with respect to the panel substrate 14, the lattice panel 15, the push button panel 16 and the rubber contacts 17. FIG. 12 shows a sectional view along the line XII-XII shown in FIG. 10. Apparently as shown in these drawings, in the lattice panel 15, the recessed parts 15 c are provided in such a manner that the void part 15 b is enlarged in the direction from each of the four corners of the void part 15 b to an intersection point of the frames 15 a of the lattice panel 15. At the recessed part 15 c, the panel substrate 14 is exposed outside of the frame 15 a of the lattice panel 15, and at the exposed part the rubber contact 17 are disposed. The push button panel 16 is disposed in the void part 15 b of the lattice panel 15 in such a manner that the extended part 16 c at each of the four corners of the push button panel 16 is engaged with the recessed part 15 c. In this way, the extended part 16 c is provided at each of the four corners of the push button panel 16 as an operation member, and the rubber contact 17 as supporting means and detecting means is provided at the lower surface side of the extended part 16 c. Because of that, it is possible to, while keeping supporting stably the push button panel, improve the sensibility of detection with respect to the push-down operation. Namely, as the push button panel 16 is supported at the four corners, it is impossible to improve the supporting stability, and as the supported point and the detected point of the push-down operation are coincident with each other, even if the push button panel 16 is pushed down obliquely to a normal line of the surface of the panel main body 16 a, it is possible to detect surely the operation by making the inside electrodes of any one of the rubber contacts 17 conduct. Moreover, as the rubber contact 17 is disposed inside the recessed part 15 c and at the lower side of the extended part 16 c of each of the four corners, there is no possibility that position gaps could happen. Therefore, it is possible to detect surely the operation. Additionally, the panel substrate 14 is covered by the frame 15 a in a region except the recessed parts 15 c. Moreover, the base 12 is also covered by the frame 15 a.

Returning to FIG. 9, on the upper surface of the lattice panel 15, the button cover 18 and the lattice cover 19 are overlaid in such a manner that the panel main body 16 a protrudes from the void parts 18 a, 19 a of the covers 18, 19. Then, a small screw is screwed in the base 12 through the button cover 18, the lattice panel 15 and the lattice base 13 sequentially from the lattice cover 19. Thereby, the input module 11 is built up integrally. In addition, by screwing a small screw in base 12 through the lattice base 13, the panel substrate 14 is fixed at a constant position. The built up input module 11 is overlaid on the display surface 10 a of the monitor 10. The monitor 10 is fixed to the control panel part 3 of the chassis 2, the input module 11 is overlaid on the display surface 10 a of the monitor 10 to screw the folding back part 12 a of the base 12 to the chassis 2. Thereby, The interface unit 4 is fixed to the chassis 2. Moreover, the frame 20 is also fixed to the monitor 10. The frame 20 extends across entire width of the monitor 10 along the boundary between the input display part 4 a and the multi purpose display part 4 b so as to partition the parts 4 a, 4 b. As shown in FIG. 1, a facing panel 5 is provided to the chassis 2 in such a manner that the facing panel 5 rims the periphery of the input display part 4 a of the interface unit 4. On the boundary between the input display part 4 a and the multi purpose display part 4 b, the facing panel 5 is fixed to the chassis 2. By such an fitting structure, while the monitor 10 is shared between all push button parts 4 c and the multi purpose display part 4 b in the input display part 4 a, it is possible to give an impression that they are different display parts from each other.

In the game machine 1 which is structured as mentioned above, by the control unit 30 provided in the chassis 2, different display control is executed between the input display part 4 a and the multi purpose display part 4 b. Moreover, a predetermined game is executed by executing display controls which are independent of each other between the push button parts 4 c in the input display part 4 a. An example of a game screen is shown in FIG. 13. In this example, an operation instruction image 31 is displayed at appropriate push button parts 4 c in the input display part 4 a, the operation instruction image 31 instructing a timing to perform the push-down operation to the push button part 4 c where the image 31 is displayed. The operation timing is predetermined, for example, to the music selected in the game. It is determined by the control unit 30 based on a contact state of the inside electrodes in the rubber contacts 17, whether or not the push button part 4 c has been pushed down to the timing instructed by the operation instruction image 31. Based on the determination result, a game score of a player is calculated. In the multi purpose display part 4 b, screen image with a different purpose from that of the input display part 4 a is properly displayed, the screen image being for example, various kinds of information to inform the player, such as a game score, operation instruction and the like, or screen image for setting the mood for the game.

The present invention is not limited to the above mentioned embodiment, and may be executed as various kinds of embodiments. For example, The number and the arrangement of the push buttons 4 c are not limited to the example shown in the drawings, and can be changed to various states. Also, the shape of the panel main body 16 a of the push button panel 16 is not limited to the square flat plate, and can be properly changed to a circle-shaped flat plate, a polygonal shape except a quadrangle or the like. Whatever the case, as long as there is provided the structure that the plural extended parts are provided at the outer periphery of the operation member, each of the extended parts is engaged with the recess part of in the void part of the partitioning member put around the periphery of operation member, and the plastic elastic body with electrodes such as a rubber contact is disposed at the lower side of the operation member, it is possible to improve the detective sensibility of the push-down operation while improving the supporting stability of the operation members. Moreover, the structure of the input module 11 as the input device is also not limited to the above mentioned embodiment, and the components such as the base and the lattice base can be properly added, deleted, and changed. The present invention is not limited to an example that the rubber contact corresponds to both of the supporting means and the detecting means, The present invention can be realized by preparing different parts corresponding to the supporting means and the detecting means respectively. Additionally, with respect to the light shielding of the boundary on the display surface between the first display part and the second display part and the boundary on the display surface between operation parts of the first display part, the embodiment is not limited to the light shielding by the base. It is possible to further improve the effects of shielding light by eliminating the regions on the display surface corresponding to the frames of the lattice panel provided on the base.
